Title: Optical disk
Inventor: SATO ISAO
IPC: G11B7/24091
Filed: 1987-02-27
Abstract: PURPOSE:To permit detection of an off-track of an erasing light beam and mis-erasing by the off-track by providing mark signals which can discriminate that a sector discriminator, data field and erasing light beam exist in adjacent tracks. CONSTITUTION:The mark signals M1, M2, etc., capable of discriminating that the sector discriminator ID, the data field DF to record data and the erasing light beam exist in the adjacent tracks are provided to the sector format of an optical disk. An address reproduction circuit 1 reads an address from the ID of a reproduction signal 100 for recording and reproducing light beams and outputs an address detection signal 103, etc. The signal 103 is then applied to an M1 gate generating circuit 2 and an M2 gate generating circuit 3. The circuits 2, 3 generate an M1 gate signal 104 and an M2 gate signal 105. The signals 104 and 105 detect that the erasing input beam exists in even or odd number tracks by separating the signals M1, M2 of a reproduction signal 101 for the erasing light beam with time. The detection of the off-track of the erasing light beam and the prevention of the mis-erasing are thereby attained.

Title: Production of wear-resisting cast copper alloy
Inventor: SUWA MASATERU
IPC: C22C1/10
Filed: 1979-04-13
Abstract: PURPOSE: To uniformly disperse graphite in a copper alloy when manufacturing a graphite-dispersed wear-resisting cast copper alloy, by using a Cu-Mn alloy containing a prescribed quantity of manganese.  
     CONSTITUTION: The surfaces of fine graphite grains are plated with Cu by a non- electrolytic plating method or the like. Reduction treatment is then effected on the gains at 350°C under an atmosphere of hydrogen for 30 minutes to produce reduced powder. The reduced graphite grains are added and stirred in a molten Cu-Mn alloy containing 10W45% by weight of Mn, under an atmosphere of the inert gas so that the graphite grains are uniformly dispersed in the alloy. Since the Cu-Mn alloy is used, Cr, Ti and Zr for improving the wetting property of the graphite to the molten copper alloy do not need to be added to the alloy. As a result, a wear- resisting cast copper alloy containing uniformly dispersed graphite can be produced not by high pressure casting but by ordinary metal mold casting.

Abstract: PROBLEM TO BE SOLVED: To provide a developing device capable of always forming an image having high image quality by controlling the bias voltage of a developing roller, so as to prevent a change in printing density occurring according to the increase of the number of prints. SOLUTION: A cumulative print number value stored in an EFPROM is read out (S1) and when the exchange of a process unit 7 is not required (S2:NO), a prescribed bias value voltage corresponding to each cumulative print number value is read from developing bias voltage information 80 stored in the EEPROM (S5).

Title: Contour correcting circuit
Inventor: MASUDA YUKIO
IPC: H04N1/409
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent image by setting a gradation conversion charac teristic of a contour part in advance and correcting a gradation conversion of a signal value of a contour part detected from an image signal based on the gradation conversion characteristics so as to suppress a pre-shoot and an overshoot. SOLUTION: A function of e.g. y=xα, that is, the α-th power of x is used for a gradation conversion characteristic. The value α is a parameter with a value being 1.0 or over to decide emphasis of a contour and an operator sets the parameter to a desired value by using a knob or the like of a variable resistor. A gradation conversion characteristic setting section 1 stores a conversion table between an input pixel value and an output pixel value after the conversion to, e.g. a lookup table in 8 bits on the basis of the set parameter α. A contour detection section 12 discriminates a part whose luminance change exceeds a prescribed value on the basis of a differentiated input video signal as a contour part and gives a pixel value of the contour part to a contour gradation correction section 13.  The contour gradation correction section 13 references the lookup table to convert the input pixel value and outputs the result as a corrected video pixel of the contour part.

Abstract: PROBLEM TO BE SOLVED: To nondestructively and accurately evaluate the degree of stabilization of the rust layer of a weather-resistant steel material by sampling the rust layer adhering to ferrite that is formed on the surface of a steel material and measuring the amount of mass change at a specific temperature or more of the sampled rust powder. SOLUTION: A rust layer that adheres to ferrite being formed on the surface of a steel material is sampled, the amount of mass change at a temperature that is equal to or more than 100 deg.C of the sampled rust powder is measured, and the degree of stabilization of the rust layer is evaluated. When rust is to be sampled, the sampling is made separately to each of surface and inner layers of rust. Then, the mass of rust per unit area (1 cm2) is found, then a rust-sampling area and the total amount of sampling (total mass) of sampled rust are determined, required rust is sampled from the determined sampling area, and thermal analysis is made to each sampled rust, thus evaluating the degree of stabilization of rust.  The amount of mass change due to a temperature change within a range of 105 to 300 deg.C caused by amorphous quantity and thermal analysis is constantly correlated according to the analysis result of the amorphous quantity by the thermal analysis and X-ray diffraction method for rust being formed at various kinds of weather-resistant steels.
